In this article we develop a new method to segment Q-Ball imaging (QBI) data. We first estimate the orientation distribution function (ODF) using a fast and robust spherical harmonic (SH) method. Then, we use a region-based statistical surface evolution on this image of ODFs to efficiently find coherent white matter fiber bundles. We show that our method is appropriate to propagate through regi...

the aesthetics of the stories of holy quran means identification of beauty and art in its expression. the quran is not a book of fictions, but its real stories, with religious and educational purpose, have artistically been expressed, with a rhetorical style and dynamic images that one can realize its artistic aspects in content and structure. the geometric structure of its stories makes it pos...

[1] Submicron atmospheric aerosol particles were collected between 1 March 2008 and 1 March 2009 at Barrow, Alaska, to characterize the organic mass (OM) in the Arctic aerosol. Organic functional group concentrations and trace metals were measured with FTIR on submicron particles collected on Teflon filters. The OM varied from 0.07 mg m in summer to 0.43 mg m in winter, and 0.35 mg m in spring,...

BACKGROUND INFORMATION The post-2015 Sustainable Development Goals for sanitation call for universal access to adequate and equitable sanitation and an end to open defaecation by 2030. In Isiolo County, a semi-arid region lying in the northern part of Kenya, poor sanitation and water shortage remain a major problem facing the rural communities. OBJECTIVE The overall aim of the study was to as...

Accumulating evidence indicates that menaquinone-4 (MK-4), a vitamin K(2) with four isoprene units, inhibits osteoclastogenesis in murine bone marrow culture, but the reason for this inhibition is not yet clear, especially in human bone marrow culture. To clarify the inhibitory mechanism, we investigated the differentiation of colony-forming-unit fibroblasts (CFU-Fs) and osteoclasts in human bo...

INTRODUCTION: The quest of diffusion-weighted (DW) imaging is to non-invasively obtain information about the average diffusion of water molecules in biological tissue. Many recent high angular resolution diffusion imaging (HARDI) [1, and references therein] techniques are proposed to infer the diffusion or fiber orientation distribution function (ODF), but this ODF only captures the angular str...

BACKGROUND In Diffusion Tensor Imaging (DTI), Riemannian framework based on Information Geometry theory has been proposed for processing tensors on estimation, interpolation, smoothing, regularization, segmentation, statistical test and so on. Recently Riemannian framework has been generalized to Orientation Distribution Function (ODF) and it is applicable to any Probability Density Function (P...

Context. Stellar spectral synthesis is essential for various applications, ranging from determining stellar parameters to comprehensive variability calculations. New observational resources as well advanced atmosphere modelling, taking three dimensional effects radiative magnetohydrodynamics calculations into account, require a more efficient transfer. Aims. For accurate, fast and flexible of o...
